Jim Katsoulis argues that sleep is the most important discipline for weight loss, more foundational than diet itself. Adequate sleep gives you the mindset and energy to make healthier choices throughout the day. Going to bed earlier ensures the rest and recovery your body needs.

The number one discipline to lose weight, and I believe this discipline is more important than even eating because it's so fundamental and foundational to everything else that impacts your weight. And what that discipline is, is sleep discipline. The ability to go to bed earlier so that you get the rest and recovery that you need so when you wake up, you have the mindset, the clarity, the energy to make the choices that allow you to live in the body you wanna live in.
